In carrying my invention into effect, I provide a tool body or stockcomprising a central portion a provided at its rear end with abackwardly directed and upwardly curved neck portion a having a handle apreferably in the form of the handle of a saw, and at its front end witha projecting head a. rounded on its outer side and pro vided with acentral pivot pin hole a The neck portion a is provided with a centrallongitudinal opening 0; above which is a raised shoulder a and saidcentral stock or body portion is also provided at the back thereof withan oblong shoulder or projection (4 and at the front thereof with acorresponding oblong recess a, and mounted in and movable horizontallythrough the central stock or body portion a, and through the oblongshoulder a at the bottom thereof is a front pin 6 and a rear pin 5 andthe top portion of the shoulder or projection a is provided with setscrew holes 5 and 5 through which are passed set screws 6 and Z) forholding the pins 6 and b at any desired point of adjustment.

The back of the shoulder a is also pro vided with a horizontal socket orrecess a adapted to receive one end of a guide and operating rod 0,shown in operative position in Fig. 1, and which will be hereinafterfully described, and the shoulder a is also provided with a set screwhole 0 through which is passed a set screw 0 by means of which the toolis secured to the rod 0.

A supplemental front stock member cl is placed in the recess a at thefront of the main central stock member a, and the pins 7) and b passthrough this supplemental stock member d, and said supplemental stockmember is secured to said pins by set screws (Z and CF, thisconstruction being clearly shown in Figs. 1, 2 and 5.

. Mounted between the main central stock member a and the frontsupplemental stock member (Z are detachable jaw plates e and f, and saiddetachable plates 6 and f are arranged in transverse pairs, two of eachbeing employed, and the pins 6 and Z2 pass through the top or headportion of the jaw members or plates 0 and f, and the lower ends ofthese jaw members or plates form guidesfor the cutter blade inthe'operation of the tool, as hereinafter described. The back sidedetachable jaw or plate members c and f are secured to the main stockmemother with a recess i through which the pin 72 passes, and said jawor plate members are also provided respectively with screw holes 6 and fthrough which the screws 6 e" and F-f are passed.

Mounted between the parts 0, and (Z of the main central stock or bodyportion and ranging downwardly and forwardly, is the cutter blade 9, andsaid cutter blade rests on and is supported by the transverse jaw orplate members f, and also rests on the raised shoulder a of the neckportion of the main stock or body, and by reason of the fact that thefront side stock member 03 is adjustable on the pins 5 and b cutterblades of different widths may be employed.

' A look lever in is pivoted betweenthe central stock members a and d,as shown at if, and the lower end if thereof bears on the lower endportion of the blade 9, and passed through the upper end portion of saidlock lever is a set screw it which bears on the upper end portion of theblade 9. This construction being well known and forming no part of myinvention. The blade 9 is also provided with an aperture or slot g andpivoted rearwardly of said blade at g is an arc-shaped lever g the frontend of which passes throughsaid aperture, and the rear end of which isprovided with a longitudinal slot 9 and passed downwardly through theraised shoulder a of the neck portion of the stock. is a screw 7.provided with a pin or similar device 6 which passes through the slot 9and the screw 2' is provided with a lock nut i which is set into thestock member of and holds said screw in said stock member and said nut iis provided with a milled head i and by turning said nut by means of themilled head it thereof, the

screw 2' may be raised or lowered as desired, and this movement ofsaid'screw will operate the lever 9* to raise or lower the cutter blade9, as may be desired, and this construction is also old and well known.

Secured to the front end portion of the main central stock member a andover the forwardly projecting head (6* thereof is a gage plate j havinga circular front portion in which is formed an arc-shaped slot j and thecircular front portion 1' is provided with a degree scale j*. The maincentral stock member a is also provided with a front supplemental headportion having a disk 70 which fits between the plate j and theprojecting head portion a, and a screw 70 is passed through the headportion a and through the disk 70 and through the plate j, and providedwith a milled nut 10*, and said supplemental head portion 70 is free torotate or turn on said screw.

A look screw 71: is passed downwardly through the slot 7' inthe plate yand into the supplemental head Z3 and serves as a lock screw for holdingsaid supplemental head at any desired point of adjustment, or at anydesired angle to the plane of the main stock portion.

A pin is is passed vertically through the end portion of thesupplemental head member 76 and is vertically adjustable therein, andmay be locked in any desired position by a set screw 7: and passedhorizontally through the supplemental headmember 7c forwardly of the pin70 is a pin k on the opposite sides of which are mounted angle plates mheld in place by blocks 70 mounted on said pin 70 and provided with setscrews 72 and the blocks A are preferably welded to the angle plates m,and said angle plates at are provided with downwardly directed guidemembers or jaws m The central supplemental stock member (Z is providedwith a large central recess m shown in Figs. 1 and 3, to permit thecuttings of' the blade 9 to pass freely upwardly, backwardly and throughthe stock, and both the central stock members a and (Z are providedbetween the pin 6 and the connection of the rod 0 with verticalapertures m and a depth gage rod wa having a bottom foot P1906 m6 may bepassed through either of these apertures, as clearly shown in Fig. 3,and used on either side of the main central stock portion of the tool inthe operation thereof, as hereinafter described, and said rod m isprovided with a suitable scale m and may be held in any desired positionin the stock, or the separate parts thereof, by a set screw m and thegage rod m may be used in cutting or forming either curved or straightmolding strips. I also provide a side guide m for use when cutting orforming straight molding strips only, and this device consists of acurved arm m having a head m through which the pins 6 or b may @bepassed, and said arm is provided at its lowerend with afoot piece madapted to bear on a molding strip a, as shownin Fig. 3, and the depthgage m is also adapted to operate in connection with said molding strip,as shown in said figure.

The method of using my improved tool or instrument for cutting orforming curved molding strips is shown in Fig. 1, and in i thisoperation, the rod 0 is used as a radius,

and as a guide for the tool or instrument, and said rod is provided witha scale 0 and is rotatably connected with a base plate or support 0secured, in practice,'to a table, work bench, or any other suitablesupport on which the molding strip to be cut or formed is also placed.

The method of or means for connecting the rod 0 with the support orplate 0 is shown in detail in Figs. 9 to 14 inclusive, and thisconnection is such as to permit of the free rotation of the rod 0 in ahorizontal plane, and also of the vertical adjustment of said rod on theplate or support 0 and this connection is also such as to permit saidrod to swing in a vertical plane. In order to accomplish this result, Iprovide a tube 0 which is secured in the base plate or support 0, andthe lower end of which is closed by a plug 0 The tube 0 is slottedvertically on opposite sides thereof, as shown at 0 in Fig. 12, and isprovided at its upper end with a closure cap 0, and passed verticallythrough said tube is a screw 0, the lower end of which is not threadedand is rotatable in the plug 0 and provided with a head 0*, and theupper end of the screw 0 is provided with a milled head 0 The rod 0 isconnected with a forked block 7) mounted on the tube 0 and comprisingparallel jaws 12 provided at one side with a projecting shoulder 39 inwhich is mounted a rotary plug 39 provided at one end with a screwthreaded shank onto which is screwed a supplemental clamp block 79through which the rod 0 passes, and said block 7) consists of twoparallel jaw members 7) through which is passed a set screw p providedwith a milled head 1)", and said rod is adjustable in the block 79", andmay be secured in any desired position therein by means of the screw 79I also provide a nut 7 having oppositely directed pin members 1", andthis nut is mounted in a ring .9 hav ing opposite side apertures 8through which the fingers r of the nut r are adapted to be passed. Theseparts are clearly shown in Figs. 10 to 14: inclusive, and said ring 8 isgreater in diameter than the nut r, and in practice, the nut r with itsfingers r is placed in the ring 8, as shown in Fig. 10, the said ringcontaining the nut is then placed between the jaws 79 of the block p,after which the block 7) is mounted on the tube 0, in which operationthe fingers 7' of the nut 1" pass through the slots 0 in said tube,after which thecap 0 is screwed onto the tube 0, and the screw 0 is thenpassed downwardly through. the cap 0 and through the tube 0, and throughthe nut r and through the plug 0 in the bottom of said tube 0, afterwhich the lower end of the screw 0 is headed or provided with a nut, asshown at 0, and these parts are thus permanently connected, and the tube0 may be secured in the base plate or support 0" in any desired manner.

In the operation of this device for cutting or forming curved moldings,as shown in Fig. 1, a molding strip a is secured in position, and theradius of the curve thereof being known, the rod 0 is adjusted in theclamp block p to correspond with said radius, and the tool proper ismanipulated by means of the handle a as will be readily understood.

A cross section of the mold strip a, shown in Fig. l, shows that theinner top portion thereof is cut away to form a flat surface a and ashoulder a. between which is a head a The blade 9, shown in the drawing,is provided at its lower end with a semi-circular recess, whereby, thehead a is formed, and in the operation of the tool, a groove 72, isformed between the bead n and the shoulder a and the jaw plates 6 and farranged in pairs transversely of the stock of the tool move in thegroove and on the outer side of the bead a and hold the tool in properposition. Before beginning this operation, the inner top portion of thestrip is cut away to form the flat surface 72. by a plane, the blade ofwhich is provided with a straight edge, and anotherblade may besubstituted for the blade g, shown and described for this purpose, andthe rod 0 may be so adjusted that the tool will first cut away the topinner surface of the molding strip to form the face a of a part thereof,to the desired depth, after which the rod 0 may be readjusted so as tobring the operative parts of the tool into the position shown in Fig. 3,in which position the head a may be formed, and in this operation, thedepth gage m may be employed, as will be readily understood.

Although I have shown said guide device m in Fig. 3 of the accompanyingdrawings, it will be understood, as hereinbefore stated, that this guidedevice is intended primarily for use in cutting or forming straightmolda ing strips, in which event, or in which on eration, the rod 0 isnot employed, and the tool 18 used in the same manner as other tools ofthis class, the straight molding the bead nas it is formed, as clearlyshown in Fig. at, and the supplemental stock head 7 member is must, inthis operation, be adjusted into the desired position, which isdetermined by the scale j on the plate j, and the parts at with whichthe guide members m are connected and to which the blocks are secured,are adjustable laterally on the pin 70*, and said guide members m arethus adjustable toward and from each other, whereby they are adapted tooperate in connection with a bead n of greater or less dimensions.

The vertically adjustable pin 70 in the supplemental: stock head is isintended for use in cutting the surface a in the top of the moldingstrip in which operation, the lower end of said pin bears on saidsurface, and this pin aids in holding the tool in proper position as itis manipulated by hand, and to maintain the proper level thereof, andwhen the guide members m are in use, in the operation of cutting orforming the bead n on a curved molding strip, the pin is is raised so asto be out of the way. It will also be understood, however, that theguide members m may be employed in forming a bead on a curved moldingstrip, and the vertically adjustable guide or gage rod is may also beused in cutting a flat surface on a curved molding strip, but the partsm and 7c are never both in use at the same time.

The rod 0 is adapted to swing in a vertical plane so as to enable themoving of the tool backwardly, conveniently, in which operation, it ispreferable to raise it off of the work piece, and said rod 0 isvertically adjustable on the tube 0 in order to adapt the tooland rod tomolding strips of different thicknesses, and it will be understood thatthe rods 0 may be of any desired length, and While I have shown anddescribed the preferred method of, and means for, connecting the rod 0with a support consisting of the parts 0 and 0, it will be understoodthat my invention is not limited to the details of construction hereinshown and described for accomplishing this object, and any suitableconstruction that will permit the rotation of said rod on its support orsupports, and the vertical adjustment thereof, and the vertical swingingmovement thereof, may be employed for this purpose, and while I havealso shown and described the preferred construction of the tool properwith which the free end of the rod 0 is c0nnected, it will be understoodthat changes in and modifications of these features of the constructionshown and described, may also be madewithin the scope of the appendedclaims.

The tool proper is also reversible on the rod 0 so that it may be usedwith either hand by the operator, and for this purpose, the

thereof, is provided withthe socket a on both sides thereof, and the setscrew 0 used in connection therewith, and it will also be seen that thedepth gage'm may be employed. on either side of the said central stockportion, including the part at, both being provided with a bore m toreceive said depth gage and corresponding set screw m for holding it inposition.

Having ,fully described my invention what I claim as'new and desire tosecure by Letters Patent is 1. In a tool of the class described, acentral. stock member provided wvith downwardly directed guidejawsarranged in transverse and converging pairs, and between which avertically adjustable cutter blade is secured,-said central stock memberbeing also provided at its front end with a supplemental stock memberrotatably adjustable thereon, and provided with downwardly directedsupplemental guiding jaws laterally adjustable.
